问HN：有没有人使用Meshtastic/LoRa进行非聊天应用？
Meshtastic在离网短信方面变得非常受欢迎，但我觉得其底层架构（LoRa网状网络 + BLE中继到手机）可以做更多的事情。
我在一个正在开发的导航应用中添加了Meshtastic支持。手机通过BLE与Meshtastic无线电通信，利用LoRa发送你的坐标，你可以在完全没有手机信号的情况下看到其他人的网格位置。从我和一小组人在森林中测试的情况来看，这实际上效果相当不错。
不过，让它正常工作可真不容易。BLE的文档很少，protobuf模式在固件版本之间不断变化，而且几乎没有关于如何将Meshtastic集成到自己应用中的资料，大家只能使用官方客户端。经历了很多的反复试验。
还有其他人在Meshtastic或LoRa网状网络上构建东西吗？传感器、追踪、紧急通信等等。你的设置是什么样的，BLE的稳定性如何？

Meshtastic has gotten really popular for off-grid texting but I feel like the underlying architecture (LoRa mesh + BLE relay to phone) could do a lot more than chat.<p>I added Meshtastic support to a navigation app I'm working on. Phone talks to a Meshtastic radio over BLE, pushes your coordinates out over LoRa, and you can see other people's grid positions with no cell service at all. It actually works pretty well from what I tested with a small group out in the woods.<p>Getting it working was a pain though. BLE docs are sparse, protobuf schemas shift between firmware releases, and there's basically nothing out there for integrating Meshtastic into your own app vs just using the official client. Lots of trial and error.<p>Anyone else building things on top of Meshtastic or LoRa mesh? Sensor stuff, tracking, emergency comms, whatever. What does your setup look like and how bad is the BLE flakiness on your end?
